Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a decorative and thermal insulation composite integrated building exterior wall panel. Background Technology

[0002] In modern architecture, decorative panels are widely used. For example, metal decorative panels, with their unique metallic texture, good durability, and relatively light weight, are widely used in building exterior wall decoration. However, the current application of decorative panels in building exterior walls has revealed many problems that urgently need to be addressed.

[0003] The problem of detached decorative panels poses a serious threat to building safety. Traditional decorative panels are typically individual pieces, usually fixed to the existing wall substrate by simple adhesives or a few mechanical connectors. Over time, the building walls shift due to factors such as temperature changes and structural deformation, gradually weakening the adhesive's bonding strength and causing the mechanical connectors to loosen. Under long-term exposure to wind, sun, and rain, the bond between the decorative panel and the substrate becomes increasingly fragile, eventually leading to panel detachment. Detached panels not only damage the building's appearance but also pose a safety hazard to pedestrians and vehicles.

[0004] In addition, the above-mentioned decorative panels are installed after the work has been completed, which requires working at height. The connection method of the decorative panels is limited by the existing working conditions, which restricts the connection method of the decorative panels.

[0005] Based on the above technical problems, there is a need for a decorative and thermally insulated composite integrated building exterior wall panel. This exterior wall panel integrates wall panel, thermal insulation and decorative functions into one, realizes the prefabricated modular design of the wall panel, makes the installation method of the decorative panel more flexible, and thus ensures a better connection effect of the decorative panel.

[0037] The decorative and thermally insulated composite integrated building exterior wall panel of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0038] As used in this invention, the singular forms “a,” “an,” and “the” include plural objects; the term “or” is generally used to mean “and / or”; the term “a number” is generally used to mean “at least one”; and the terms “at least two” or “more than” are generally used to mean “two or more”. Furthermore, the terms “first,” “second,” and “third” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with “first,” “second,” or “third” may explicitly or implicitly include one or at least two of that feature. Furthermore, the terms "installed," "connected," and "attached," as used in this utility model, and the term "set" on one element from another, should be interpreted broadly. They generally only indicate a connection, coupling, cooperation, or transmission relationship between the two elements, which can be direct or indirect through an intermediate element. They should not be construed as indicating or implying a spatial positional relationship between the two elements, meaning one element can be located inside, outside, above, below, or to one side of the other element, unless otherwise explicitly stated. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances. Additionally, directional terms such as above, below, up, down, upward, downward, left, and right are used relative to exemplary embodiments as shown in the figures, with upward or up direction pointing towards the top of the corresponding figure, and downward or down direction pointing towards the bottom of the corresponding figure.

[0039] Combination Figure 1 and Figure 2 As shown, this embodiment provides a decorative and thermally insulated composite integrated building exterior wall panel, including a wall panel unit 100; the wall panel unit 100 includes a wall panel assembly 10, a finishing layer 20, and connectors 30.

[0040] The wall panel assembly 10 includes a concrete base back panel 11 and an insulation layer 12, wherein the insulation layer 12 is attached to one side of the concrete base back panel 11.

[0041] The concrete base back plate 11 serves as the main body of the entire building's exterior wall panel, ensuring structural strength and stability.

[0042] The concrete backing plate 11 is made of concrete of appropriate strength grade, medium sand, fibers, and additives such as admixtures (the proportion of additives can be configured based on the crack resistance and waterproof performance of the concrete backing plate 11). These are mixed in a specific ratio, poured into a mold, pressed, and cured to produce a concrete backing plate 11 that meets the design thickness and dimensions. The concrete backing plate 11 requires a smooth surface and certain strength and stability. Existing materials can be selected for the concrete backing plate 11 based on requirements. The materials and manufacturing process of the concrete backing plate 11 are existing technologies and will not be elaborated here.

[0043] The insulation layer 12 is made of high-efficiency insulation material with a honeycomb structure to ensure low thermal conductivity and provide good thermal insulation effect. The insulation layer 12 has a fire performance rating of B1 or above to ensure its flame retardant effect. The insulation layer 12 is attached to the concrete base plate 11. The insulation layer 12 can be made of materials such as polyurethane foam, expanded polystyrene (EPS), or phenolic foam, and the material can be selected based on actual usage requirements. The thickness, fire resistance rating, and other parameters of the insulation layer must meet the design standards.

[0044] The finishing layer 20 is located on the side of the insulation layer 12 away from the concrete base plate 11, and the finishing layer 20 is connected to the concrete base plate 11 and the insulation layer 12.

[0045] In this embodiment, the finishing layer 20 is connected to the concrete base plate 11 and the insulation layer 12 by mechanical bonding. In other alternative embodiments, the finishing layer 20 may be connected to the concrete base plate 11 or the insulation layer 12 separately.

[0046] The finishing layer 20 can be made of metal sheet of appropriate specifications, and surface treated to give it properties such as beauty, weather resistance, and self-cleaning.

[0047] For example, the decorative layer 20 is an aluminum plate that has been treated with fluorocarbon spraying, and the surface is pre-processed with threaded holes for mechanical connection with the insulation layer. The fluorocarbon spray coating has a thickness of 25-35μm. As an anti-corrosion layer, the fluorocarbon coating has good resistance to ultraviolet rays and acid and alkali corrosion.

[0048] The connector 30 is connected to the concrete base plate 11 to connect the concrete base plate 11 to the main structure of the building. Preferably, a portion of the connector 30 is embedded in the concrete base plate 11, and another portion is exposed on the outside of the concrete base plate 11. When the above-mentioned decorative and thermal insulation composite integrated building exterior wall panel serves as the building exterior wall, the building does not require a base wall; the exterior wall can be directly attached to the main structure of the building via the connector 30.

[0049] The connector 30 can be a metal hook or other metal connector, and the specific structural form of the connector 30 can be set based on its connection method. The connection method between the connector 30 and the concrete base plate 11 can also be adjusted according to actual needs.

[0050] The preferred concrete base plate 11 is provided with connectors 30 at the nodes in both the horizontal and vertical directions. Multiple connectors 30 are used to achieve multi-point connection with the main building structure to ensure sufficient connection strength.

[0051] The aforementioned decorative and thermal insulation composite integrated building exterior wall panel is prefabricated and modular, and can be prefabricated in the factory. The installation method of the finishing layer 20 is not limited by the on-site construction conditions, making the installation method of the finishing layer 20 more flexible. By selecting a suitable connection method, a better connection effect of the finishing layer 20 can be ensured, thereby improving the phenomenon of the finishing panel falling off.

[0052] The aforementioned decorative and thermal insulation composite integrated building exterior wall panel can be used as a building exterior wall. This building exterior wall panel integrates wall panel, thermal insulation and decorative functions into one, realizing the prefabricated modular design of the wall panel. It can be directly connected to the main building, and the connection process does not rely on the building foundation wall, which helps to improve on-site construction efficiency.

[0053] Please continue to refer to this. Figure 1 As shown, the wall panel assembly 10 also includes a moisture-proof vapor barrier layer 13, which is disposed on the concrete base backing plate 11 and located between the concrete base backing plate 11 and the insulation layer 12. The moisture-proof vapor barrier layer 13 is laid flat, without wrinkles or damage, and is fixed to the concrete base backing plate 11 with a special adhesive to ensure its airtightness.

[0054] In this embodiment, the moisture-proof vapor barrier 13 is made of aluminum foil with a thickness of not less than 0.05 mm, used to prevent moisture from entering the insulation layer and affecting the insulation effect. In other alternative embodiments, the moisture-proof vapor barrier 13 can be made of other known waterproof materials.

[0055] Please continue to refer to this. Figure 1 and Figure 2 As shown, the finishing layer 20 includes a finishing body 21 and a bent portion 22 connected to the edge of the finishing body 21. The finishing body 21 is located on the side of the insulation layer 12 away from the concrete base plate 11, and the bent portion 22 wraps around the side of the wall panel assembly 10. Here, the side refers to the position of the edge of the wall panel assembly 10 parallel to its wall panel direction.

[0056] In this embodiment, the wall panel assembly 10 is a rectangular structure. Figure 1 and Figure 2In this context, the orientation of the building's exterior wall panels when they are hung on the main structure of the building is taken as the reference (at this time, the overall orientation of the building's exterior wall panels is vertical). Figure 1 The first direction 'a' corresponds to the length direction of the wall panel assembly 10, and is also the horizontal direction parallel to its wall panels. Figure 2 The second direction b corresponds to the vertical direction of the wall panel assembly 10, which is also parallel to the wall panel.

[0057] Therefore, the wall panel assembly 10 of the above shape has four sides ( Figure 1 The left and right sides of the middle and Figure 2 (The upper and lower sides of the wall panel assembly 10). The main body of the cladding 21 is located on the exterior side of the entire building's exterior wall and serves a decorative function. The main body of the cladding 21 is provided with four bent parts 22 corresponding to the four sides of the wall panel assembly 10. The four bent parts 22 respectively wrap around the four sides of the wall panel assembly 10.

[0058] In other alternative embodiments, the wall panel assembly 10 can be of other shapes, such as a pentagon. In this case, the wall panel assembly 10 has five side edges, so the decorative body 21 is provided with five bends 22 to wrap around the sides of the wall panel assembly 10. The specific shape of the wall panel assembly 10 can be adjusted according to its usage requirements, and the distribution of the bends 22 can also be adjusted according to the actual shape of the wall panel assembly 10.

[0059] In this embodiment, the decorative and thermal insulation composite integrated building exterior wall panel includes multiple wall panel units 100, and each of the wall panel units 100 is arranged vertically and horizontally.

[0060] Multiple wall panel units 100 can be connected together by a keel frame, or multiple wall panel units 100 can be connected to the main building on the construction site.

[0061] Figure 1 The diagram shows the structure of the junction of two horizontally arranged (along the first direction a) wall panel units 100. Figure 1 The right side of the wall panel unit 100 located on the left is adjacent to the left side of the wall panel unit 100 located on the right. The structure of the right side of the wall panel unit 100 is the same as that of the right side of the wall panel unit 100 located on the left, and similarly, the structure of the left side of the wall panel unit 100 located on the left is the same as that of the left side of the wall panel unit 100 located on the right.

[0062] Figure 2 The diagram shows the structure of the junction of two vertically arranged (along the second direction b) wall panel units 100. Figure 1The bottom of the upper wall panel unit 100 is adjacent to the top of the lower wall panel unit 100. The structure of the top portion of the upper wall panel unit 100 is the same as the structure of the top portion of the lower wall panel unit 100, and similarly, the structure of the bottom portion of the lower wall panel unit 100 is the same as the structure of the bottom portion of the upper wall panel unit 100.

[0063] In other alternative embodiments, each of the wall panel units 100 may be only along the vertical direction ( Figure 2 The second direction (b) or the horizontal direction ( Figure 1 The first direction a) arrangement setting, the number of wall panel units 100 and the specific arrangement method can be adjusted based on actual usage needs.

[0064] Combination Figure 1 As shown, taking the left side of the wall panel unit 100 on the right as an example, the bending part 22 includes a first bending part 221 and a second bending part 222 that are connected to each other. The first bending part 221 and the second bending part 222 are set at an angle. The bending part 22 here is integrally formed with the decorative body 21.

[0065] In this embodiment, the first bending portion 221 and the second bending portion 222 are perpendicular to each other, forming an approximately "L" shaped structure. The first bending portion 221 is perpendicular to the concrete base plate 11 and is attached to the left side of the wall panel assembly 10. The second bending portion 222 is attached to the side of the concrete base plate 11 away from the insulation layer 12 (i.e., attached to the side of the concrete base plate 11 closer to the interior) and is connected to the concrete base plate 11.

[0066] like Figure 1 As shown, a connecting hole is provided on the back of the second bend 222. The second bend 222 is connected to the concrete base plate 11 by a bolt passing through the connecting hole to form a mechanically fixed connection. This ensures a reliable connection between the finishing layer 20 and the wall panel assembly 10.

[0067] Combination Figure 2 As shown, taking the top portion of the lower wall panel unit 100 as an example, the bending portion 22 here includes a first bending portion 221 and a second bending portion 222 connected to each other, with the first bending portion 221 and the second bending portion 222 arranged at an angle. The bending portion 22 here is an independent component, which is connected to the decorative body 21 by mechanical connection.

[0068] Figure 2The first bend 221 and the second bend 222 are perpendicular to each other, forming an approximately "L" shaped structure. The first bend 221 is perpendicular to the concrete base plate 11 and is attached to the top of the wall panel assembly 10. The second bend 222 is attached to the side of the concrete base plate 11 away from the insulation layer 12 (i.e., attached to the side of the concrete base plate 11 closer to the interior) and is connected to the concrete base plate 11.

[0069] like Figure 2 As shown, a connecting hole is provided on the back of the second bend 222. The second bend 222 is connected to the concrete base plate 11 by bolts passing through the connecting hole to form a mechanically fixed connection. This ensures a reliable connection between the finishing layer 20 and the wall panel assembly 10. Preferably, the second bend 222 is connected to the concrete base plate 11 by multiple bolts, with a spacing of 200mm between adjacent bolts.

[0070] Similarly, the right side and bottom of the wall panel assembly 10 have a wrapping structure similar to the aforementioned bent portion 22. Each bent portion 22 is connected to the concrete base plate 11, so that the surrounding area of ​​the finishing layer 20 is connected to the concrete base plate 11 to ensure good connection strength.

[0071] The wrapping fit between the decorative layer 20 and the wall panel assembly 10 protects the sides of the wall panel assembly 10, ensuring the overall structural strength of the entire wall panel unit 100. Simultaneously, this wrapping fit naturally creates a structural connection between the decorative layer 20 and the wall panel assembly 10. The decorative layer 20 is seamlessly connected to the wall panel assembly 10 via the bending portion 22, ensuring good connection stability. Furthermore, the bending portion 22 can be further connected to the concrete base plate 11 using bolts or other mechanical connection methods, further ensuring good connection stability of the decorative layer 20 and effectively solving the problem of decorative panel detachment.

[0072] In addition, the finishing layer 20 can also be connected to the wall panel assembly 10 by means of adhesive bonding.

[0073] At least a portion of the decorative layer 20 is bonded to the insulation layer 12. In this embodiment, the decorative body 21 can be bonded to the insulation layer 12, and the bent portion 22 is mechanically connected to the wall panel assembly 10.

[0074] The thermal insulation layer 12 is bonded to the concrete base plate 11. Furthermore, the moisture-proof vapor barrier layer 13 is bonded to the concrete base plate 11, and the thermal insulation layer 12 is bonded to the moisture-proof vapor barrier layer 13.

[0075] Preferably, the adhesive used between the decorative surface 21 and the insulation layer 12 is a polyurethane adhesive, and the tensile bond strength of the polyurethane adhesive is not less than 0.5 MPa. The adhesives used between the moisture-proof vapor barrier layer 13 and the concrete base plate 11, and between the insulation layer 12 and the moisture-proof vapor barrier layer 13, are polymer cementitious adhesives. The tensile bond strength of the polymer cementitious adhesive is not less than 1.0 MPa.

[0076] The aforementioned building exterior wall, with its finishing layer, insulation layer, and concrete base plate, is integrated into one unit through adhesives and mechanical connectors, ensuring good consistency of the building exterior wall and making the connections between the various components of the building exterior wall panel tight.

[0077] Combination Figure 2 As shown, the wall panel unit 100 also includes a reinforcement member 40, which is connected to the upper edge of the concrete base plate 11 and the insulation layer 12, and the bending portion 22 is connected to the reinforcement member 40.

[0078] In this embodiment, the reinforcement 40 has an approximately "U" shaped structure. The reinforcement 40 is inserted into the top of the insulation layer 12, and the first bent portion 221 is horizontally attached to the closed end of the reinforcement 40. Figure 2 The upper end of the reinforcement component 40), one side of the reinforcement component 40 ( Figure 2 The right side of the reinforcement 40 is bolted to the outdoor side of the concrete base plate 11, and the other side of the reinforcement 40 is also bolted to the outdoor side. Figure 2 The left side of the middle) is attached to the finishing layer 20, and the finishing layer 20 and the reinforcement 40 are connected together to the outside of the insulation layer 12 by bolts. Figure 2 (Left side of the intermediate insulation layer 12). The reinforcement components serve two purposes: firstly, to reinforce the wall panel assembly 10, and secondly, to connect the air duct to the finishing layer 20.

[0079] In other alternative embodiments, the reinforcement 40 may be connected only to the upper edge of the concrete base plate 11 or the insulation layer 12.

[0080] Please continue to refer to this. Figure 2 As shown, there is a connection between the finishing layers 20 of adjacent wall panel units 100.

[0081] The finishing layer 20 is provided with a slot 23 near its top. In the vertically adjacent wall panel units 100, the bottom of the finishing layer 20 of the upper wall panel unit 100 is engaged in the slot 23 of the finishing layer 20 of the lower wall panel unit 100.

[0082] like Figure 2As shown, the top of the decorative body 21 of the decorative layer 20 is provided with an upward-opening, approximately "U"-shaped slot 23. The slot 23 is formed by bending a separate decorative panel and is integrally formed with the bent portion 22 located at the top.

[0083] The lower end of the decorative body 21 of the decorative layer 20 has an elastic bending portion 26, which is integrally formed with the lower end of the decorative body 21. The elastic bending portion 26 has an acute angle clamping bending structure.

[0084] In the adjacent wall panel units 100, the elastic bending part 26 of the upper wall panel unit 100 is located in the slot 23 of the lower wall panel unit 100, and the bottom of the decorative body 21 of the upper wall panel unit 100 abuts against the opening side of the slot 23, so that the adjacent wall panel units 100 form an elastic snap-fit ​​structure with precise positioning and tight connection.

[0085] Please refer to Figure 1 As shown, there is a connection between the finishing layers 20 of horizontally (along the first direction a) adjacent wall panel units 100.

[0086] The finishing layer 20 is provided with a first fastening groove 24 and a second fastening groove 25, the first fastening groove 24 and the second fastening groove 25 being located on both sides of the finishing layer 20 along the horizontal direction parallel to the concrete base back plate 11 (both sides along the first direction a).

[0087] like Figure 1 As shown, the right side of the finishing layer 20 of the wall panel unit 100 on the left is provided with a second fastening groove 25, and the left side of the finishing layer 20 of the wall panel unit 100 on the right is provided with a first fastening groove 24. The first fastening groove 24 is opened towards the interior, and the second fastening groove 25 is opened towards the exterior.

[0088] In the horizontally adjacent wall panel units 100, the right side portion of the left wall panel unit 100 is located within the first fastening groove 24 of the right wall panel unit 100, and the left side portion of the right wall panel unit 100 is located within the second fastening groove 25 of the left wall panel unit 100, wherein the first fastening groove 24 is covered outside the gap between the horizontally adjacent wall panel units 100.

[0089] The aforementioned connection method allows the decorative panels of horizontally adjacent wall panel units 100 to interlock, creating a recessed relationship and enriching the facade. Furthermore, this interlocking relationship provides mutual protection between the gaps between horizontally adjacent wall panel units 100, while also ensuring a good decorative effect.

[0090] Please refer to Figure 1 and Figure 2As shown, the decorative and thermal insulation composite integrated building exterior wall panel also includes a sealing element 50, which is disposed in the gap between adjacent wall panel units 100, and the gap is about 1.5 to 2 cm.

[0091] In this embodiment, the sealing element 50 is disposed in the gap near the indoor side. The sealing element 50 includes a backing material 51 and a sealant 52. The backing material 51 fills the gap between adjacent wall panel units 100. The backing material 51 is used to fill the gap and assist in sealing. The sealant 52 seals the backing material 51 near the indoor side, thereby sealing the gap between adjacent wall panel units 100. The sealant 52 needs to have good adhesion and waterproof properties.

[0092] In this embodiment, the backing material 51 is preferably an existing waterproof backing material, such as TPO waterproof membrane. This material typically has high tensile strength, high tear strength, fatigue resistance, and puncture resistance, effectively preventing water penetration and maintaining long-term waterproof function. In other alternative embodiments, the backing material 51 can also be an epoxy resin backing material, etc., and the specific material can be selected based on the application requirements.

[0093] Furthermore, the decorative and thermally insulated composite building exterior wall panel also includes a fireproof and thermally insulated material 60, which is disposed between adjacent wall panel units 100, and the sealing element 50 is located on the side of the fireproof and thermally insulated material 60 closer to the concrete base back plate 11 (i.e., on the indoor side of the gap). The placement of the fireproof and thermally insulated material 60 helps to enhance the fireproof and thermally insulated effect at the gap between adjacent wall panel units 100.

[0094] In this embodiment, the fireproof and thermal insulation material 60 is selected from existing fireproof and thermal insulation cotton to enhance the fireproof and thermal insulation effect. In other alternative embodiments, the fireproof and thermal insulation material 60 can be selected from materials such as polyurethane foam, expanded polystyrene (EPS), and phenolic foam, and the specific material can be selected based on actual needs.

[0095] In this embodiment, preferably, sealing elements 50 and fireproof and heat-insulating materials 60 are provided between horizontally adjacent wall panel units 100 and between vertically adjacent wall panel units 100 to ensure waterproofing and airtightness, and to enhance the overall structural connection strength.

[0096] During the installation and fabrication of the aforementioned decorative and thermal insulation composite integrated building exterior wall, a moisture-proof vapor barrier layer 13 is first laid on the concrete base plate 11. It should be ensured that the moisture-proof vapor barrier layer 13 is laid flat, without wrinkles or damage, and fixed with a special adhesive to ensure its airtightness.

[0097] The prepared insulation layer 12 is laid on the moisture-proof vapor barrier layer 13. Adhesive can be used to enhance the connection and ensure that the insulation layer 12 and the moisture-proof vapor barrier layer 13 are tightly bonded.

[0098] Install the reinforcement member 40, which is inserted into the upper end of the insulation layer 12, with one side embedded in the insulation layer 12 or between the insulation layer 12 and the concrete base plate 11. Secure one side of the reinforcement member 40 to the concrete base plate 11 with bolts to ensure a firm connection.

[0099] The finishing layer 20 is installed on the wall panel assembly 10, wherein the bent portion 22 of the finishing layer 20 wraps around the side of the wall panel assembly 10, and the finishing layer 20 is connected to the reinforcement member 40 and the concrete base plate 11. The spacing and position of the connecting bolts must meet the design requirements to ensure the overall structural stability of the wall panel.

[0100] Position the wall panel unit 100 and connect it to the main building structure via connector 30. For the gaps between adjacent wall panel units 100, first fill with backing material 51, then apply sealant 52, and finally fill with fire-resistant and thermal insulation material 60. The sealant 52 should be applied evenly to ensure a tight seal and prevent rainwater and air penetration.

[0101] Check the flatness and verticality of each wall panel unit 100 using tools such as a straightedge and theodolite. If any deviations are found, adjust them promptly to ensure that the wall panel installation meets the acceptance standards.

[0102] A visual inspection is conducted on the installed decorative and insulated composite building exterior walls, cleaning surface stains and excess sealant to ensure a clean appearance. Waterproofing and airtightness tests are performed, such as water spray tests and airtightness testing equipment, to ensure the wall panels meet the design requirements. Any problems found are repaired promptly.

[0103] In terms of existing building exteriors, current facade designs are relatively monotonous. Most projects only pursue basic functional fulfillment, lacking innovation in styling and often employing simple flat panel splicing or regular arrangements, failing to meet the increasingly diverse aesthetic demands of architecture. For landmark buildings or projects pursuing unique styles, this monotonous facade design cannot fully showcase the building's personality and charm, limiting the creative expression of architectural design. However, the decorative and thermally insulated integrated building facade of this utility model, employing a modular prefabricated structure, allows for diverse facade forms, facilitating innovative styling, and the placement of the finishing layer 20 is not limited by construction conditions, thus satisfying the increasingly diverse aesthetic needs of architecture.

[0104] Furthermore, the unreliability of the sealant application process is another key factor affecting the performance of exterior walls. In actual construction, the quality of sealant application is constrained by a variety of factors. The temperature and humidity of the construction environment significantly affect the curing and bonding effect of the sealant. If sealant is applied in an unsuitable environment, problems such as incomplete curing and weak bonding may occur. Moreover, the sealant application process requires a high level of technical skill from the construction personnel. Slight carelessness in operation can lead to defects such as uneven sealant joints and residual air bubbles, resulting in a significant reduction in waterproofing and airtightness. Over time, the sealant will also lose its elasticity and adhesion due to aging, ultraviolet radiation, and other factors, further reducing the waterproofing and airtightness of the exterior walls. Problems such as rainwater leakage and air infiltration will follow, increasing building energy consumption and reducing indoor living comfort.

[0105] The decorative and thermal insulation composite integrated building exterior wall of this utility model adopts a modular prefabricated structure. A sealing element 50 is set between adjacent wall panel units 100. The setting of the sealing element 50 is less affected by on-site construction. Moreover, the sealing element 50 is located on the inner side of the decorative and thermal insulation composite integrated building exterior wall, which can be installed inside the building, making the caulking process more flexible.

[0106] This utility model discloses a decorative and thermally insulated integrated building exterior wall, which consists of an aesthetically pleasing, weather-resistant, and self-cleaning decorative layer, a high-efficiency thermal insulation layer, and a concrete base panel to ensure strength. These components are bonded together using adhesives and mechanical connectors. Connectors and sealants at horizontal and vertical joints ensure waterproofing, airtightness, and structural stability. During production, the materials are prefabricated and composited in the factory. During installation, the integrated exterior wall can be directly installed and fixed to the main structure, supplemented by tongue-and-groove connections, sealant filling, and metal trim decoration. This integrated exterior wall offers convenient construction, shortens the construction period, reduces costs, and significantly improves thermal insulation, waterproofing, airtightness, and structural stability, making it suitable for various modern building exterior wall projects.

[0107] The decorative and thermal insulation composite integrated building exterior wall of this utility model can effectively solve the problem of decorative panel detachment, enrich the appearance of buildings, and ensure reliable waterproof and airtight performance.

[0108] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0109] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
